I just read an article about billionares. This says that most of them (775) are still in Europe but the USA will most likely take the lead in 2017. Now there is 571 billionares in the USA, says Helsingin Sanomat (27.5.2015).
Europe’s billionares are the richest of them. There are many billionares also in China, Great Britain and Germany.
In Europe, only 17% of the billionares have made their own money. The rest of them became billionares by inheritance. In the USA almost 50% have made their fortune themselves and in Asia almost one third.
It looks like that the USA will take the lead in mumber of billionares soon because the biggest growing group of billionares are the ones that make their own money and the USA has clearly the most of that type.
Nine out of ten billionares are men. Only 13% of these men became billionares by inheritance. Their average age is 64 years and almost 90% of them are married.
One out of ten billionares is a woman. The average billionare woman is 61 years old and inherited her billions. Only on third of bilionare women have made their own money at least partially. Women who have built their assets themselves are clearly younger than their inheritance-enjoying counterparts and their property is very much less of value.
Here is the complete article in Finnish with more details http://www.hs.fi/talous/a1432617093969
